I am baffled any time I’m on facebook how horrid it is. Loads insanely slowly, won’t accept picture uploads at random, randomly doesn’t let you share to people in your friends group (it will just hide people for no reason). Such a terrible website. Sadly I have to stay on it for friends and music reasons (there is nothing else anyone I know uses) but man, it’s crazy how badly they want you to install their spyware app so you don’t use the browser version.
I made a frontend for Instagram, and the code is similarly dogshit.
Hashtags have IDs, which are fetched, then the hashtag is fetched with that id.
Also, Instagram rapidly spams itself with requests of you try to browse comments when logged out
Also, the vast majority of requests (aside from media/assets) are just tracking.
